Abstract
Description
Technical Field
[0001] This invention relates to the field of medical equipment technology, specifically to a gastric tube and urostomy bag bridging drainage system. Background Technology
[0002] Post-colostomy defecation difficulties are a pressing nursing challenge in clinical practice, and their pathogenesis exhibits a multifactorial interaction. Pathologically, this may involve stoma anatomical abnormalities (such as stoma stenosis or retraction), intestinal motility disorders (altered peristaltic rhythm or pelvic floor muscle coordination dysfunction), and outlet obstruction. Physiologically, it is closely related to insufficient dietary fiber intake, fluid loss, and altered bowel habits. Clinical management follows a stepwise approach, prioritizing conservative treatments such as laxatives, intestinal microecological regulation, and stoma irrigation. Surgical intervention is only cautiously considered when conservative treatment fails or signs of intestinal obstruction appear. Notably, the anatomical remodeling and altered defecation reflex pathways caused by the interruption of digestive tract continuity often lead to a triple predicament: progressive decline in intestinal motility, hardened stool, and mechanical obstruction of the stoma. This complex defecation disorder not only significantly reduces patients' quality of life but may also induce serious complications such as intestinal pressure injury and electrolyte imbalance.
[0003] Current techniques typically require removing the ostomy bag and manually assisting with defecation, which can lead to fecal leakage, unpleasant odors, and significant damage to the patient's self-esteem. Therefore, there is an urgent need for a stoma drainage technique to address defecation difficulties caused by stoma outlet obstruction, constipation in stoma patients, and insufficient intestinal motility.

[0031] Beneficial effects of this invention:
[0032] This invention proposes a gastric tube and urostomy bag bridging drainage system. Based on the existing urostomy bag structure, the system adjusts the stoma base structure to bridge the gastric tube, and introduces a ring-shaped drainage component, a dilution sleeve, and an infusion dilution component. Diluent is provided through the gastric tube and the infusion dilution component. The dilution sleeve is installed into the gastric tube, and combined with the ring-shaped drainage component, it dilutes feces inside and outside the stoma, softening the feces into a liquid state, which is then transferred to the drainage bag through the urostomy bag. This drainage system, through the bridging structure of the gastric tube and the dilution sleeve, features a double-layer dilution sleeve. The double-layer dilution sleeve includes an inner layer and an outer layer that are interconnected and nested, both hollow internally, and have multiple second drainage holes. The system features a double-layered dilution sleeve fitted over the gastric tube extending from the stoma. The outer layer's inner side abuts against the outer wall of the gastric tube, while the inner layer's outer side abuts against the inner wall. The gastric tube is then partially retracted into the stoma. This structure allows the diluent introduced through the gastric tube and the infusion dilution unit to be introduced into and around the stoma, further integrating the diluent with the stool to be expelled, achieving softening and liquefaction, rather than merely treating the stool on the stoma surface. This effectively lubricates bowel movements for obstructed patients, improving overall defecation efficiency. Furthermore, the entire drainage process is a closed-loop transfer, preventing leakage and protecting the patient's dignity. Attached Figure Description

[0041] Example
[0042] Existing technologies typically employ external physical interventions to assist defecation, such as removing the ostomy bag and manually flushing and cleaning to soften the stool, followed by manual collection. However, this procedure is highly prone to damaging the stoma and can lead to fecal leakage, significantly impacting the patient's self-esteem. Therefore, this embodiment proposes a gastric tube and urinary tract ostomy bag bridging drainage system, such as... Figure 1 and Figure 2 As shown, Figure 1 This is an assembly diagram of the internal structure of the ostomy bag after it has been concealed. Figure 2 The assembly diagram for use includes a stoma base plate 1, a ring-shaped drainage assembly, a urinary tract stoma bag 14, a drainage bag 9, an infusion dilution assembly, and a first dilution kit.
[0043] The stoma base plate 1 has a stoma opening for attaching to the stoma; the annular drainage assembly is hollow inside, and its bottom is detachably connected to the stoma base plate 1; one end of the urostomy bag 14 is fixedly fitted onto the annular drainage assembly; the drainage bag 9 is connected to the other end of the urostomy bag 14 via a drainage tube 8; the infusion dilution assembly is connected to the annular drainage assembly via an infusion tube to provide diluent; the first dilution sleeve is placed inside the urostomy bag 14 to ultimately perform the dilution action. The diluent in the infusion dilution assembly is liquid paraffin and physiological saline.
[0044] like Figure 3 As shown, Figure 3This is a partial structural diagram of the stoma base. The first dilution kit includes a first dilution ring 4 and a double-layer dilution sleeve 20. The first dilution ring 4 is connected to the annular drainage assembly and is mounted above the stoma opening. The first dilution ring 4 has multiple first drainage holes facing the stoma opening. The double-layer dilution sleeve 20 is connected to the first dilution ring 4 and includes an inner layer and an outer layer that are interconnected and nested together. Both layers are hollow inside. When fitted onto the gastric tube 10 extending from the stoma, the inner side of the outer layer abuts against the outer wall of the gastric tube 10, and the outer side of the inner layer abuts against the inner wall of the gastric tube 10. Multiple second drainage holes are provided on the outer side of the outer layer and the inner side of the inner layer of the double-layer dilution sleeve 20. A double-layered dilution sleeve 20 is fitted onto the gastric tube 10 extending from the stoma. The inner side of the outer layer abuts against the outer wall of the gastric tube 10, and the outer side of the inner layer abuts against the inner wall of the gastric tube 10. The gastric tube 10 is then partially retracted into the stoma. This structure allows the diluent introduced through the gastric tube 10 and the infusion dilution assembly to be introduced into and around the stoma, further integrating the diluent with the stool to be expelled, achieving softening and liquefaction, rather than merely treating the stool on the stoma surface. This effectively lubricates and improves overall defecation efficiency for obstructive patients. Liquid paraffin is injected into the gastric tube 10 for intestinal lubrication.
[0045] To facilitate the installation and adjustment of the ostomy bag, a first rubber ring 11 is fixed on the ostomy base plate 1 in this embodiment. Specifically, the annular drainage assembly includes an adjustment assembly, a fluid storage ring, and two fluid guide plates 13. The fluid storage ring is an adjusting toothed ring 12 with teeth on the outer side.
[0046] The adjusting gear ring 12 is hollow inside; a limiting rubber ring 17 is fixed inside the adjusting gear ring 12; the radius of the limiting rubber ring 17 is larger than that of the first rubber ring 11, and its cross-sectional diameter is smaller than that of the first rubber ring 11; when the adjusting gear ring 12 is engaged with the stoma base plate 1, the limiting rubber ring 17 engages and rotates against the outside of the first rubber ring 11; two fluid guiding plates 13 are respectively fixedly installed on the fluid storage ring and communicate with the adjusting gear ring 12; one end of the urostomy bag 14 is sealed to the two fluid guiding plates 13 and the adjusting gear ring 12. The adjusting assembly includes a gear 15 and an adjusting nut 16. Wherein, as Figure 3 As shown, gear 15 is rotatably mounted on stoma base 1 and meshes with adjusting gear ring 12; adjusting nut 16 is fixedly connected to gear 15. In the above structure, a detachable sealed connection is achieved by elastically engaging the limiting rubber ring 17 on adjusting gear ring 12 with the first rubber ring 11 on stoma base 1. This connection method ensures easy disassembly while maintaining a seal, and also allows for angle adjustment, ensuring that the entire urostomy band 14 can hang downwards for easy collection of diluted feces. The adjustment is achieved by rotating adjusting nut 16, based on the transmission between gear 15 and adjusting gear ring 12. Furthermore, the first dilution ring 4 is connected to a guide plate 13 via connecting pipe 3; the first dilution ring 4 is an arc-shaped ring, and the opening of the arc-shaped ring is vertically downwards through the adjusting component, making the opening of the first dilution ring 4 an opening to avoid diluted feces.
[0047] Furthermore, to prevent blockage caused by the introduction of the urostomy bag 14 into the drainage bag 9 through the drainage tube 8, the present invention also includes a second dilution assembly; the second dilution assembly includes a conical tube 7, a second dilution ring 6, and a first flexible tube 5. The diluent is provided by the infusion dilution assembly. Specifically, the larger radius end of the conical tube 7 is connected to the other end of the urostomy bag 14, and the other end is connected to the drainage bag 9 through the drainage tube 8; the second dilution ring 6 is located inside the urostomy bag 14 and is fixedly installed at the larger radius end of the conical tube 7, and has a third outlet hole facing the axis of the conical tube 7; the first flexible tube 5 is located inside the urostomy bag 14 and is connected to another guide plate 13 and the second dilution ring 6. The diluent provided by the infusion dilution assembly is further guided to the connection between the conical tube 7 and the drainage tube 8 through the first flexible tube 5, further diluting the feces so that it can smoothly enter the drainage tube 8 and be collected by the drainage bag 9, improving the collection efficiency of the feces.
[0048] To improve the installability of the double-layer dilution sleeve 20, such as Figure 3 and Figure 4 As shown, one end of the inner and outer layers of the double-layer dilution sleeve 20 is connected by two fixing pieces; the outer layer of the double-layer dilution sleeve 20 is connected to the first dilution ring 4 through a second flexible tube 19; the other end of the outer layer is fixed with a second rubber ring 18 for elastic fixation to the gastric tube 10. Figure 4 This is a side view of part 1 of the stoma chassis structure.
[0049] Furthermore, the infusion dilution assembly includes an infusion tubing connection 2 and an infusion set. The infusion tubing connection 2 is connected to a guide plate 13; the infusion set is detachably connected to the infusion tubing connection 2 via an infusion bottle and an infusion tubing, providing physiological saline and liquid paraffin for dilution. To facilitate observation of stool collection and whether stool blockage has occurred, the urostomy bag 14 and drainage bag 9 are made of transparent plastic.
[0050] The specific execution steps of this embodiment include the following steps:
[0051] S1: Attach the stoma base plate 1 to the stoma site and extend the gastric tube 10 out of the stoma.
[0052] S2: Install the double-layer dilution sleeve 20 mounted on the adjusting toothed ring 12, and fit the double-layer dilution sleeve 20 onto the gastric tube 10, and use the second rubber ring 18 for elastic fixation.
[0053] S3: Install the adjusting toothed ring 12, and make a detachable sealing connection by elastically engaging the limiting rubber ring 17 on the adjusting toothed ring 12 with the first rubber ring 11 on the stoma base plate 1.
[0054] S4: Connect the drainage bag 9 through the drainage tube 8.
[0055] S5: Rotate the adjustment component to make the opening of the arc ring vertically downward, and use the opening of the first dilution ring 4 as an opening to avoid the diluted feces.
[0056] S6: The 10-part gastric tube is returned to the stoma. Liquid paraffin is injected into the gastric tube three times a day, 50 ml each time, to lubricate the intestines and soften the stool.
[0057] S7: Use the infusion dilution device to inject normal saline to dilute the feces. The normal saline rate is increased from 50ml / h to 150ml / h and maintained for 4 hours until 500ml of saline is dripped through. This is done twice a day. The feces will be discharged from the stoma and flow into the drainage bag 9.
[0058] In this embodiment, the system is based on the existing ostomy bag structure. By adjusting the structure of the stoma base plate 1 and bridging it with the gastric tube 10, a ring-shaped drainage component, a dilution sleeve, and an infusion dilution component are further introduced. Diluent is provided through the gastric tube 10 and the infusion dilution component. The dilution sleeve is installed on the gastric tube 10, and combined with the ring-shaped drainage component, the feces inside and outside the stoma are diluted. This process softens and liquefies the feces, allowing them to be transferred to the drainage bag 9 through the ostomy bag. This drainage system utilizes the bridging structure between the gastric tube 10 and the dilution sleeve, designing a double-layer dilution sleeve 20. The double-layer dilution sleeve 20 consists of an inner layer and an outer layer, which are interconnected and nested together. Both layers are hollow internally and have multiple second drainage holes. The double-layer dilution sleeve 20 is fitted onto the gastric tube 10 extending from the stoma. At this time, the inner side of the outer layer contacts the outer wall of the gastric tube 10, and the outer side of the inner layer contacts the inner wall of the gastric tube 10. Subsequently, section 10 of the gastric tube is retracted to the stoma, through which diluted fluid is guided into and around the stoma, further mixing with the stool to be expelled, achieving softening and liquefaction. This mechanism not only targets the stool on the stoma surface but also effectively helps obstructed patients lubricate their bowel movements, improving overall defecation efficiency. Simultaneously, the entire drainage process employs a closed transfer method to ensure no leakage occurs, thereby protecting the patient's dignity.
[0059] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
